String Telephones in Year 4!

Nov 24, 2022Science

Year 4 have loved putting their knowledge of sound and states of matter to the test by making string telephones. We already knew that sounds are made by vibrations, which pass on to the surrounding air particles before travelling into our ear. Our string telephones allowed us to talk to each other from 10 metres away, as the sound passed through the solid string (as a solid’s particles are close together). It was great fun testing out how well our telephones worked!
